Analyzing Simplified Work
Ben simplified this expression.
Analyze Ben's work. Did he simplify the expression
correctly? If not, what was his mistake?
O Yes, he is correct.
No, he needed to add the exponents of powers of
the same base in the first step
No, he needed to apply the exponent to all factors
in the product in the second step.
O No, he needed to simplify further by subtracting the
exponents of the powers,
X

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
